Categorizing Expenses in QuickBooks

A simple guide for small business owners who want clean, accurate books

If you use QuickBooks Online, you’ve probably seen that long list of categories and thought:

“Am I putting this in the right place?”

You’re not alone!

Categorizing expenses correctly is one of the most important parts of bookkeeping, and one of the most confusing for small business owners.

Let’s simplify it.

What Does “Categorizing” Mean in QuickBooks?

When money leaves your business account, QuickBooks asks you to assign it to a category.

That category tells QuickBooks:

• What the money was spent on

• Where it shows up on your Profit & Loss

• Whether it affects profit

• How it’s treated for tax purposes

Think of categories as labels that organize your financial story.

Why Proper Categorization Matters

If your categories are wrong:

• Your Profit & Loss won’t reflect reality

• You won’t know where you’re overspending

• Your tax preparer may have to fix things (which costs you more)

• You could miss legitimate deductions

• Or worse, deduct things you shouldn’t

Clean categories = clean reports = better decisions.

The Main Expense Categories Most Businesses Use

Here’s a simple breakdown of common categories in QuickBooks:

Advertising & Marketing

• Facebook ads

• Website hosting

• Business cards

• Flyers

Auto Expense

• Fuel

• Oil changes

• Repairs

• Insurance (if vehicle-specific)

(If you use the mileage method, you typically won’t deduct fuel separately.)

Supplies

• Cleaning products

• Small tools

• Office supplies

• Materials used for jobs

If supplies are directly tied to revenue, you may want them under Cost of Goods Sold (COGS) instead.

Software & Subscriptions

• QuickBooks

• Scheduling apps

• Canva

• Email marketing tools

Insurance

• General liability

• Professional insurance

• Bonding

Professional Services

• Bookkeeper

• CPA

• Legal services

Meals

Business-related meals only — not your lunch from Tuesday.

Equipment

Small tools = expense
Large purchases = may need to be categorized as Fixed Assets

Expense vs. Asset What’s the Difference?

This is where many people get tripped up.

Expense:

Something used up within the year
Example: cleaning supplies, subscriptions, fuel

Shows up on your Profit & Loss immediately.

Asset:

Something that lasts multiple years
Example: truck, commercial mower, large equipment

Goes on your Balance Sheet and may be depreciated.

If a purchase is over ~$2,500, it’s worth asking your CPA how to handle it.

How to Categorize in QuickBooks (Step-by-Step)

1. Go to Banking > For Review

2. Click on a transaction

3. Choose the correct Category

4. Add a description or memo if needed

5. Click Confirm

You can also create Rules to auto-categorize repeat transactions.

Example:

• If Description contains “Shell” Auto-categorize as Fuel

This saves time and keeps things consistent.

Common Categorizing Mistakes

❌ Dumping everything into “Miscellaneous Expense”
❌ Mixing personal and business transactions
❌ Deducting mileage AND fuel
❌ Never reconciling after categorizing
❌ Changing categories randomly each month

Consistency matters more than perfection.

A Simple Goal to Aim For

When someone looks at your Profit & Loss, they should be able to clearly see:

• How much you made

• What you spent

• Where your money went

• Whether you made a profit

If your categories support that clarity then you’re doing it right.

Final Thoughts

QuickBooks isn’t just about tracking transactions.
It’s about telling the financial story of your business.

And proper categorization is what makes that story clear, accurate, and useful.
